Installing a Two Post Lift: Stage 1. THE CONCRETE!!

This is the first part of a series of what it takes to turn your garage into a shop with a Two Post Lift. The first stage I cover the concrete and why the foundation is the most important. We poured this to 8" using 5k psi concrete for my lift. I took out the old concrete and re-poured a new slab making sure it's at least 8" throughout. You'll be surprised at the inconsistencies in thickness of existing concrete. Some parts were not even two inches thick!

Super cool, man! Hope to have a lift soon myself. Getting ideas from you.

Thanks this is one project I have been looking forward to doing, I hope these videos help. Thanks for watching and don't forget to subscribe an hit the notification for the upcoming video on the lift. I'm trying to get as many subscribers as you one day. Be Safe and Good Luck on you projects.

Im in the process of doing almost exactly to same thing in order to install my lift, drilled ny holes and found out my slab is only 3" deep, just cut the slab and over the next week im going to be digging it up, not fun haha nice video!

[@thediycontractor7034]

Good luck! I'm glad the video helped. It is good you checked your concrete thickness, always better safe than sorry!!

I watched a lot of these car post videos. The car lift measurements are precise because of that why would you not eliminate a long and irritating step. That step is embedding the bolts into the concrete now while you're pouring the concrete obviously you measure it correctly and precisely but the pros outweigh the cons. To drill deal with the heartache is eliminated The bolts are already embedded in the ground and because you would use l-shaped bolts you don't have to use the friction ones that depending how you drill that hole might come out

[@thediycontractor7034]

Sometime you don't finalize the position and location until the slab is finished, in my case I move it in about 3" which would have put my bolts in the wrong location, so I would suggest unless you are positive down too the inch put the bolts in last. Thanks for Watching!!

It takes a ton of preparation to get anchors fixtures in the right place and then your fixture is in the way of finishing the concrete which is just as important. It is doable but lot's more can go wrong.

[@PTRRanger951]

99% of lift manufactures do not use pre placed and embedded bolts. It is all drill and use anchor bolts.

2.5 yards from a concrete company would have taken much less time and been roughly $400 bucks for the concrete itself.

[@thediycontractor7034]

Fortunately for this project the concrete was free and it gave us a chance to show that you can mix it by hand if you decide. Thanks for Watching!!

[@davesdrone3125]

@@thediycontractor7034 nice, cant beat free!

[@stevec326]

You effectively changed the psi rating of that concrete down to about 2000 psi with all that water. Probably less.

[@philbar9094]

Also, most lift manufacturers specifically state to not hand mix the concrete since you will get variables like not enough slump or not thoroughly mixed.

[@stevec326]

@@philbar9094 I plan to use a power mixer rented from Home Depot because even if it was ok to do, I'm not hand mixing 27 bags of concrete! LOL

hello, what is the depth of the floor cast?

[@thediycontractor7034]

The slab is 8 Inches thick. Thanks for watching!!

[@stevepope5484]

Pretty

Thanks for Watching!!

[@henrymiecz8566]

No No No. It was all good except when you hand mixed the concrete on the floor! Come on all that work only to screw it up like that. It needs to come from a concrete mixer at 3k-4k psi. They should have underpinned the new under the old.

[@thediycontractor7034]

Fortunately for this project the concrete was free and it gave us a chance to show that you can mix it by hand if you decide. We did underpin the old concrete to the new as well as use wire screen to tie it all together. Thanks for Watching!!

[@garagekeys]

I am not liking the hand mixing, especially for a lift install

[@thediycontractor7034]

Thanks for Watching!!

[@Tackla77]

You would have been better off leaving it the way it was. Pretty sure your repair is weaker than what you had

[@thediycontractor7034]

Unfortunately it was cracked and it was less than 3inches in some places. Thanks for watching don't forget to subscribe!!
